论文摘要
在我们目前的最佳宇宙学模型中，宇宙中的绝大多数物质都是黑暗的，由未发现的非巴里型颗粒组成，这些颗粒不会相互作用。到目前为止，如星系旋转曲线或重力透镜效应所观察到的，在其重力相互作用中发现了暗物质的唯一重要证据。推断的暗物质团聚遵循几乎可以在模拟中重现的通用质量密度曲线，但从理论观点避免了解释。放弃标准（Astro-）物理方法，我表明可以从有趣的简单数学方法中得出这些概况，该方法直接决定了无碰撞暗物质颗粒的自我磨损集合的最可能的空间配置。
In our current best cosmological model, the vast majority of matter in the Universe is dark, consisting of yet undetected, non-baryonic particles that do not interact electro-magnetically. So far, the only significant evidence for dark matter has been found in its gravitational interaction, as observed in galaxy rotation curves or gravitational lensing effects. The inferred dark matter agglomerations follow almost universal mass density profiles that can be reproduced well in simulations, but have eluded an explanation from a theoretical viewpoint. Forgoing standard (astro-)physical methods, I show that it is possible to derive these profiles from an intriguingly simple mathematical approach that directly determines the most likely spatial configuration of a self-gravitating ensemble of collisionless dark matter particles.
